Several things can cause the problem. First, spring for a new spark plug. The stock plug is NGK
CR8E. Now the plug is eliminated as a problem. Next, pull the slide out of the throat of the carb
. Now remove the jet needle. Put the needle clip on the 4th notch, (this is the stock setting). Use only premium gas. Next, follow the starting instructions below.
There is a proper way to start the engine. Four controls are on your bike to assist in starting.
Don't kick, instead, push the kick lever downward. You will feel the back pressure as the piston is going upward on the compression stroke to the point the pressure is great enough that the kick lever "locks up". You are very close to TDC. NOW, pull in the de-compression lever. Push the kick lever a little bit more to get the piston past TDC. Give the throttle a 1/4 turn then let it snap closed. A diaphragm in the carb gives a shot of gas when this is done. DO NOT do this multiple times because you will flood the engine. Leave the throttle closed when kicking. Release the de-compression lever and give a strong kick through the full sweep of the kick start lever. Quickly get your foot off the kick lever at the end of the kick to avoid any chance of "kickback" from a backfire. It can be very painful, and can even break a leg. I am serious about that. Repeat the process (but without the throttle priming), until the bike starts. A good battery and clean air filter will also aid in starting.
This will likely tame the beast for you. Please rate this answer. Thanks!
- The choke, used when the engine is cold. Pull the red knob for choke.
- The " Hot Start " Lever, used when the engine is hot. Pull the lever to lean the fuel mix when the engine has been running.
- The de-compression lever, always used.
- The throttle, used to prime the cylinder.
